gIn 7 = In 14
g = In 14/In 7
g = 1.356
2) 6^(u) = 22
u In 6 = In 22
u = In 22/In 6
u = 1.725

The table is completed as follows using the double-declining-balance method of depreciation:
Year Cost Accumulated Book Value Depreciation Accumulated Book

B.O.Y E.O.Y E.O.Y
1 $30,000 $0 $30,000 $12,000 $12,000 $18,000

3 $30,000 $19,200 $10,800 $4,320 $23,520 $6,480
The double-declining-balance approach is what?
The double-declining-balance method is one of the depreciation techniques in use, however it adds additional costs in the first years of an asset's life.
In this depreciation method, the straight-line rate, which is computed as the product of 100/estimated useful life multiplied by 2, is twice.
At the conclusion of each year, the leftover balance for the depreciation charge is adjusted using the double rate.
The difference between the closing balance from the previous year and the residual value is used to determine the depreciation charge for the most recent year.
Auto = $30,000
Estimated useful life = 5 years
Residual = $800
Depreciable amount = $30,000 - $800 = 29,200
Straight-line depreciation rate = 100/5 = 20%
Double-declining depreciation rate =20% x 2 = 40%
Depreciation Expense:
1st year = 30,000 x 40/100 = 12,000
2nd year = 18,000 x 40/100 = 7,200
3rd year = 10,800 x 40/100 = 4,320
4th year = 6,480 x 40/100 = 2,592
5th year = 3,888 x 40/100 = 1,555

Estimate the average by first rounding to the nearest 100:
120, 230, 455, 175
Answer:
250.
Step-by-step explanation:
First we need to round to the nearest 100:
120 rounded to the nearest 100 is 100.
230 rounded to the nearest 100 is 200.
455 rounded to the nearest 100 is 500.
175 rounded to the nearest 100 is 200.
So, we have the numbers 100, 200, 500, and 200.
To find the average of numbers, we need to add them up and divide the number we get by how many numbers we added:
100 + 200 + 500 + 200 = 1,000
Since we added 4 numbers, we divide by 4:
1,000 divided by 4 = 250.
We don't round to the nearest 100 for 250 because the question said to only round for the original numbers. But, if i am wrong somehow, 250 rounded is 300.

Triangle ABC has the following angle measures:
mLA = (x + 6)°, mzB = (3x - 15)°, mzC = (5x +36)°
What is m/C?
The value of ∠C: 121°
What is Triangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane.
Given this,
There is an ABC triangle.
m∠A = (x + 6)°
m∠B = (3x - 15)°
m∠C = (5x + 36)°
The size of C must be determined.
Having said that,
A triangle's total number of angles equals 180 degrees.
As a result, we can say,
∠(A) + ∠(B) + ∠(C) = 180
(x + 6)° + (3x - 15)° + (5x + 36)° = 180°
(x + 3x + 5x) + (6 - 15 + 36) = 180°
9x + 27 = 180°.
9x = 180 - 27
9x = 153 degrees
x = 153/9 degrees
17 = x.
Hence,
The ∠C is expressed as
∠C = 5x + 36
= 5*17 + 36
= 85 + 36
∠C = 121.
Thus, ∠C = 121.

What is the maximum height?
The rocket reaches its maximum height at second(s) after launch.
(Simplify your answer.)
The maximum height reached by the object is feet.
(Simplify your answer.)"
The time taken for the rocket to reach its maximum height according to information given is; 2.25 seconds.
The maximum height reached by the toy rocket is; 88 feet.
What is the maximum height reached by the rocket?It follows from the task content that the maximum height reached by the rocket is to be determined.
The given function is; h (t) = -16 t² + 72t + 7.
Since it follows from evaluation that; at maximum height, the rate of change of height to time is equal to 0.
Therefore; at maximum height;
h'(t) = 0
h'(t) = -32t + 72 = 0
-32t = -72
t = -72/-32
t = 2.25 seconds.
Therefore, the time taken for the rocket to reach its maximum height is; 2.25 seconds.
Also, the maximum height reached by the rocket is at; h (2.25);
h(2.25) = -16(2.25)² + 72 (2.25) + 7
= -81 + 162 + 7

1) The equivalent fraction is 27/8, so the correct option is A.
2) The value of the exponent in the right side must be y = 2, the correct option is C.
How to find an equivalent fraction?1) First we want to find an equivalent fraction to (2/3)^(-3)
Remember that a negative exponent means that we nee to take te inverse, we can write:
(2/3)^(-3) = (3/2)^3
Now we can just distribute the exponent along the numerator and denominator.
(3/2)^3 = (3^3)/(2^3) = 27/8
The correct option is A.
2) How to find the value of y?
Here we have the equation:
(3^3)^2/9^2 = 3^y
If we move the denominator to the right side, we can write:
(3^3)^2 = 9^2*3^y
Now, remember that:
9 = 3^2
Then we can write the right side as:
(9^2)*3^y = (3^2)^2*3^y = 3^(2*2)*3^y = 3^(4 + y)
Replacing that in the original equation we get:
(3^3)^2 = 3^(4 + y)
The exponent in the left side can be rewritten as:
(3^3)^2 = 3^(3*2) = 3^6
The the equation becomes:
3^6 = 3^(y + 4)
This is only true if:
6 = y + 4
6 - 4 =y

Responses
I can’t be confident at all; this is about as close to a random guess as you can get.
I can be a little confident; it might be close, or it might be way off.
I can be very confident; it will be close, but it probably won’t be exact.
I can be certain that my predicted value will match the actual value exactly.
The correct option regarding the correlation coefficient is that A. I can’t be confident at all; this is about as close to a random guess as you can get.
What is a correlation coefficient?The correlation coefficient is a statistical measure of the strength of a two-variable linear relationship. Its values can range between -1 and 1. A correlation coefficient of -1 denotes a perfect negative, or inverse, correlation, in which values in one series rise while those in the other fall, and vice versa.
A coefficient of one indicates that there is a perfect positive correlation, or a direct relationship. A correlation coefficient of 0 indicates that no linear relationship exists. In science and finance, correlation coefficients are used to assess the degree of association between two variables, factors, or data sets.
In this case, the fat that the person gets 0 implies that it's probably a random guess. In conclusion, the correct option is A.

All the answers to the given questions are mentioned below -
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given are six graphs as shown in the image.
PART [1]The equation of graph [1] -
m = (- 2 - 4)/(2 - 0)
m = -6/2
m = -3
Equation : y = -3x + 4
The equation of graph [2] -
m = (0 + 1)/(2.5 - 0)
m = 1/2.5
m = 10/25
m = 2/5
Equation : y = 2x/5 - 1
The equation of graph [3] -
Equation : y = 4
The equation of graph [4] -
Equation : x = 2
PART - [2][1] : 2x - y = - 7
y = 2x + 7
[2] : 5x + 3y = 12
3y = -5x + 12
y = -5x/2 + 4
[3] : x - y = 1
y = x - 1
[4] : x - 3y = - 15
3y = x + 15
y = x/3 + 5
[5] : 8x - 10y = 20
8x - 20 = 10y
y = 4x/5 - 2
[6] : 14x + 6y = 36
6y = -14x + 36
y = -7x/3 + 6
Therefore, all the answers to the given questions are mentioned above.
